aid: ausperbio name: AusperBio description: 'AusperBio — AusperBio Therapeutics, Inc. in the United States and Ausper Biopharma Co., Ltd. (杭州浩博医药有限公司) in Hangzhou, China — is a clinical-stage biopharmaceutical company founded in 2019 that develops oligonucleotide and targeted delivery technologies, with an initial focus on achieving a functional cure for chronic hepatitis B infection. Its proprietary Med-Oligo antisense oligonucleotide (ASO) platform pairs novel ASO design and optimization with targeted delivery conjugation chemistry, and its Au-HALO hepatocyte-targeting delivery technology extends the same modular approach to siRNA. The lead candidate AHB-137 is an unconjugated ASO that completed enrollment in two Phase II trials and received China CDE clearance to enter Phase III; a second clinical candidate, AHB-171, is a hepatocyte-targeted siRNA. The company has raised more than $200M across Series B, B+ and B2 rounds from investors including Qiming Venture Partners, HanKang Capital, CDH Investments, Sherpa Capital, YuanBio Venture Capital and Genesis Capital. AusperBio sells therapeutics, not software: it publishes no developer program, no public API, no SDK and no machine-readable API contract. Its only machine-readable surface is the private Spring Boot CMS backend that renders ausperbio.com, whose springdoc API description is correctly locked behind authentication.' image: https://www.ausperbio.com/favicon.ico url: https://raw.githubusercontent.com/api-evangelist/ausperbio/refs/heads/main/apis.yml x-type: company x-source: harvest:secondary-market x-tier: profile x-tier-reason: no-api-surface specificationVersion: '0.23' created: '2026-08-06' modified: '2026-08-06' tags: - Company - Biotechnology - Pharmaceuticals - Biopharmaceutical - Life Sciences - Therapeutics - Oligonucleotide - Antisense Oligonucleotide - siRNA - Clinical Trials - Hepatitis B - Drug Development - Health - China apis: [] maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io common: - type: DomainSecurity url: security/ausperbio-domain-security.yml - type: Website url: https://www.ausperbio.com/ - type: About url: https://www.ausperbio.com/company.html - type: Team url: https://www.ausperbio.com/leadership.html - type: Product url: https://www.ausperbio.com/platform.html description: Med-Oligo ASO platform and Au-HALO targeted delivery technology. - type: Research url: https://www.ausperbio.com/pipeline.html description: Clinical pipeline — AHB-137 (ASO) and AHB-171 (siRNA) for chronic hepatitis B. - type: Blog url: https://www.ausperbio.com/news.html - type: News url: https://www.ausperbio.com/news.html - type: Support url: https://www.ausperbio.com/contact-us.html - type: Contact url: https://www.ausperbio.com/contact-us.html - type: Careers url: https://www.ausperbio.com/careers.html - type: TermsOfService url: https://www.ausperbio.com/term.html - type: PrivacyPolicy url: https://www.ausperbio.com/privacy.html - type: LinkedIn url: https://www.linkedin.com/company/ausperbio - type: LLMsTxt url: llms/ausperbio-llms.txt x-enrichment: date: '2026-08-06' status: minimal artifacts_added: 2 pass: local-v1 x-coverage: state: none reason: not-a-software-company detail: >- AusperBio develops antisense-oligonucleotide and siRNA drugs for chronic hepatitis B, so there is no software product to expose; ausperbio.com is a Vue single-page app that returns an identical 2,601-byte shell (md5 519d85ce…) for every path including invented ones, and the only machine-readable API description on the estate is the springdoc description of the private Spring Boot CMS at cms.ausperbio.com/jzy-admin/, which is correctly 401-gated and is site infrastructure rather than a product surface. evidence: - url: https://www.ausperbio.com/openapi.json status: 200 note: Soft 404 — byte-identical to the SPA shell returned for a nonexistent control path. - url: https://www.ausperbio.com/definitely-not-a-real-path-zzz999 status: 200 note: Control path proving every 200 on this host is the SPA catch-all. - url: https://www.ausperbio.com/llms.txt status: 200 note: Soft 404 — SPA shell, not an llms.txt. - url: https://www.ausperbio.com/.well-known/agent-card.json status: 200 note: Soft 404 — SPA shell, not an agent card.
